Chronic Obstructive Pulmonary Disease (COPD)
What is Chronic Obstructive Pulmonary Disease (COPD)?
Chronic Obstructive Pulmonary Disease, or COPD, is a long-term lung condition that makes breathing difficult. The disease damages the airways and air sacs in your lungs over time. This damage prevents air from flowing in and out as it should.
COPD includes two main conditions that often happen together. Emphysema destroys the walls between air sacs in your lungs. Chronic bronchitis causes ongoing inflammation and mucus buildup in your breathing tubes. Both conditions block airflow and reduce oxygen levels in your blood.
COPD develops slowly, usually over many years. Most people notice symptoms after age 40. The condition cannot be cured, but early detection and treatment can slow its progression. Understanding your risk factors and getting tested can help you protect your lung health before symptoms become severe.
Symptoms
- Shortness of breath, especially during physical activities
- Wheezing or a whistling sound when breathing
- Chronic cough that produces mucus
- Chest tightness or pressure
- Frequent respiratory infections
- Fatigue and lack of energy
- Unintended weight loss in later stages
- Swelling in ankles, feet, or legs
- Blue-tinted lips or fingernails from low oxygen
Many people ignore early COPD symptoms because they develop gradually. You might think breathlessness is just a normal part of aging or being out of shape. This delay in recognition often means the disease has caused significant lung damage before diagnosis.

Causes and risk factors
Smoking tobacco is the leading cause of COPD, accounting for up to 90 percent of cases. Cigarette smoke damages the delicate tissues in your lungs and airways. The longer you smoke and the more you smoke, the higher your risk becomes. Secondhand smoke exposure also raises your risk significantly.
Other risk factors include long-term exposure to air pollutants, chemical fumes, or dust in the workplace. A genetic condition called Alpha-1-Antitrypsin deficiency causes COPD in some people even without smoking. This protein normally protects your lungs from damage. Without enough of it, your lungs become vulnerable to disease. Age, history of childhood respiratory infections, and asthma can also increase your risk of developing COPD.
How it's diagnosed
Doctors diagnose COPD using a breathing test called spirometry, which measures how much air you can breathe out and how quickly. This test shows whether your airways are blocked. Your doctor will also ask about your symptoms, smoking history, and exposure to lung irritants.
Blood tests play an important role in understanding COPD and its causes. Rite Aid's preventive health panel measures key biomarkers that relate to lung health. These include Alpha-1-Antitrypsin levels to check for genetic deficiency, Carbon Dioxide to see if your body is retaining CO2, Hematocrit to measure oxygen-carrying capacity, and Myeloperoxidase to assess lung inflammation. Testing these markers helps identify your risk factors and monitor disease progression. Getting tested regularly at Quest Diagnostics locations near you can catch problems early.
Treatment options
- Quit smoking immediately and avoid secondhand smoke exposure
- Use prescribed bronchodilator inhalers to open airways
- Take inhaled corticosteroids to reduce lung inflammation
- Get vaccinated against flu and pneumonia annually
- Exercise regularly to strengthen breathing muscles
- Eat a nutrient-dense diet with plenty of fruits and vegetables
- Practice breathing exercises and pulmonary rehabilitation
- Use supplemental oxygen therapy if oxygen levels are low
- Avoid air pollution, chemical fumes, and other lung irritants
- Take antibiotics when bacterial infections occur

Frequently asked questions
The earliest signs include a chronic cough that produces mucus, shortness of breath during routine activities, and wheezing. Many people dismiss these symptoms as signs of aging or being out of shape. If you smoke or have smoked in the past and notice these symptoms, talk to a doctor. Early detection allows for treatment that can slow disease progression.
COPD cannot be cured, and lung damage cannot be reversed. However, treatment can slow the disease and improve your quality of life. Quitting smoking is the most important step you can take. Medications, pulmonary rehabilitation, and lifestyle changes help manage symptoms and prevent further damage.
Blood tests measure biomarkers that reveal lung health and inflammation. Alpha-1-Antitrypsin testing identifies genetic deficiency that causes COPD. Carbon Dioxide levels show if your lungs are retaining CO2 properly. Myeloperoxidase indicates lung inflammation levels. These tests help doctors understand your risk factors and monitor disease activity.
Alpha-1-Antitrypsin is a protein that protects your lungs from damage. People born with deficiency of this enzyme lack proper lung protection. This can lead to COPD even in non-smokers, often at a younger age. A simple blood test can identify this genetic condition and guide treatment decisions.
If you smoke or have a family history of COPD, annual testing helps track lung health markers. Rite Aid's preventive health service includes two tests per year. Regular monitoring of inflammation markers and blood gases can catch changes early. Your doctor may recommend more frequent testing if you have active symptoms or genetic risk factors.
Exercise is one of the most helpful treatments for COPD. It strengthens your breathing muscles and improves oxygen use. Start slowly with activities like walking and gradually increase duration. Pulmonary rehabilitation programs teach you safe exercises and breathing techniques. Talk to your doctor about creating an exercise plan that works for your fitness level.
Quitting smoking is by far the most important change you can make. Avoiding air pollution, dust, and chemical fumes protects your lungs from further damage. Eating a nutrient-rich diet supports lung tissue health. Staying active improves breathing capacity and overall strength. These changes can slow disease progression and reduce symptom severity.
Advanced COPD can damage lungs so severely that they cannot absorb enough oxygen from air. Supplemental oxygen ensures your organs and tissues get the oxygen they need to function. Your doctor will measure your blood oxygen levels to determine if you need oxygen therapy. Using oxygen as prescribed can improve energy, sleep quality, and longevity.
Healthy lungs remove carbon dioxide from your blood when you exhale. COPD-damaged lungs struggle to expel CO2 efficiently. This can cause CO2 to build up in your bloodstream, a condition called hypercapnia. Blood tests measuring carbon dioxide help doctors assess how well your lungs are working and guide treatment decisions.
Myeloperoxidase is an enzyme released during inflammation in your body. COPD causes chronic inflammation in the lungs and airways. This ongoing inflammation leads to elevated Myeloperoxidase levels in the blood. Measuring this biomarker helps doctors assess disease activity and inflammation levels. High levels may indicate more aggressive disease requiring adjusted treatment.
